Abstract:

Lithium-ion capacitors represent novel power storage devices amalgamating the features of both lithium-ion batteries and supercapacitors. However, the sluggish dynamics of the lithium-ion capacitor's battery-type negative electrode, compared to the capacitor-type positive electrode, lead to a diminished power density and compromised cycle stability. Notably, porous carbon-based materials derived from metal-organic frameworks (MOFs) have emerged as a focal point in electrochemical energy storage research owing to their expansive specific surface area, porous structure, and exceptional chemical stability. This study analyzes the challenges associated with electrode materials of lithium-ion capacitors and elucidates the energy storage mechanism of lithium-ion capacitors. Subsequently, the influence of carbonization temperature and heat treatment time on the physicochemical properties of MOF-derived porous carbon-based materials is examined. Moreover, diverse products generated through the carbonization process are discussed. Furthermore, the advancements in utilizing MOF-derived porous carbon-based materials in lithium-ion capacitors are reviewed. Finally, the crucial role of composite or doping modifications with other carbon materials in improving the power and energy densities for anode materials of lithium-ion capacitors is emphasized.
